摘要： A resin component for encapsulating a semiconductor includes magnetic powder and silica powder whose average particle diameter is smaller than the average particle diameter of the magnetic powder. Thus, the curing body of the resin component for encapsulating a semiconductor has an electromagnetic wave shielding function by the magnetic powder. Since the spaces of the magnetic powder are filled with the silica powder whose average particle diameter is small, the moldability of the curing body is improved and the insulating characteristics thereof are enhanced. Such a resin component for encapsulating a semiconductor is employed, there can be produced a preferably formed and encapsulated semiconductor device having the electromagnetic wave shielding function and having no malfunction generated due to leakage current from a semiconductor element.

摘要： There is disclosed a thinner-layered radio wave absorber having high absorption performance for a high frequency electromagnetic wave. The radio wave absorber, even when having a magnetic layer of not more than 1 mm in thickness, achieves satisfactory absorption characteristics for the high frequency electromagnetic wave by adopting a structure that a conductor is fixedly attached to a face opposite to an electromagnetic-wave incident face of the magnetic layer of single-layered structure, and also arranging the magnetic layer to have values of a real part &mgr;′ and an imaginary part &mgr;″ of complex relative magnetic permeability of the magnetic layer satisfying an expression of &mgr;″≧m&mgr;′−n (m: real number of m>0, n: real number of n≧0) outside an impedance mismatching region.
